Rich Chocolate Cake Made With Oats: Mistakes to Avoid

  1. No compromise in type and quality of chocolate: For smooth, decadent, rich chocolate cake, it is imperative to choose premium-quality chocolate. Any compromise on this step can change the outcome significantly.
  2. Avoid overmixing: Overmixing hardens the texture of the cake, and it often leads to dry cakes. It also works against the leavening agents and meddles with the rising of the brownies.
  3. Avoid overheating chocolate chips: Melted chocolates are a must for almost every chocolate-based sweet recipe. Therefore, perfect chocolate melting is crucial to achieve the desired consistency and texture. Overheating always burns the chocolates and alters the final taste.
  4. Avoid overbaking: Overbaking can completely ruin a moist cake. Just a few extra minutes in the heated oven, and your cake loses its consistency and texture, and turns out to be dry and hard. Take them out of the oven when they still have a wiggle in the middle.
  5. Avoid wet environments and moisture: Moisture is the biggest enemy of chocolate-based desserts. While making the batter, even a small amount of water can lead to lumpy chocolates. To ensure the chocolate is not ruined, use dry bowls, spoons, and molds.
  6. Avoid using cold ingredients: Using ingredients at room temperature is crucial, as the addition of cold ingredients like cream or butter to melted chocolate can cause the chocolate to split and form an uneven texture.
